Plextor 708A problems!

I just started having some issues with my Plextor 708A, it had worked fine when I got it a few months ago and now it takes about 45mins+ to burn a dvd-r and now I can’t even burn cd-r’s after the other day. I haven’t tried a dvd-r since the cd-r failed but I think that it would do the same.

I tried doing the DMA trick that I had found here and even doing the registry edits and none of them worked and I ended uyp having some problem with my system and having to restore it with a backup I made. I says that it’s in PIO mode only and if I change it to DMA it won’t read any disc and just spins up and eventually will switch back to PIO.

Does anyone have any thoughts as what to do??

Oh yeah using Win XP SP1 and firmware V1.08

Welcome, InvisSoul!

I suggest running the PX-708A self-test diagnostics with a piece of Plextor recommended media, as described in the manual. This should help you determine whether the fault is in the PX-708A, or something else within your system may have malfunctioned. If the self-test fails with Plextor recommended media it’s a pretty clear-cut case of drive failure.

Transfer mode switching back to PIO is not a good sign. Other than your PX-708A being suspect, try checking your IDE cables. Also, post some more information about your system: motherboard/chipset names, how your HDD and PX-708A drives are connected to the IDE bus, what CD/DVD burning software are installed, etc.

Well I did do a test the other day with Sony media and it went fine, I know thats not a recommended company but I had it handy.

I have Asus A7V600, VIA KT600 (Northbridge) and VIA VT8237 (Southbridge) chipsets. I originally had my dvd drive as master on the second ide and a HDD as slave, then I switched them around so the dvd was slave and the HDD master but no change and it’s a brand new cable ATA-133.

I have Nero 6.3.1.20 and dvd decrypter installed.

XP dropping down from UDMA to PIO is a sign that Windoze has detected too (CRC?) many errors coming through the IDE channel and is “downshifting” to a more stable transfer rate. The fact it takes so long to burn is either indicative of either the problem, or the fact that PIO is now the new default transfer method/rate.

By “registry tricks” did you mean fooling Windoze into forgetting about the downshift? I’m pretty sure I read about something very similar in the BenQ forum … try a search on “PIO” there. Sorry I can’t be more help than that.

do the self diagonostic test…make sure you’re using the latest via chipset drivers…set the 708A to secondary master…

Have you tried connecting your HDD as primary master, and the PX-708A as secondary master? For performance reasons it is best to separate the HDD and DVD writer into different IDE channels.

You can use either a 40-conductor or 80-conductor IDE cable for the PX-708A, but these days I use 80-conductor IDE cables for HDDs and all opticals, as these cables deliver better signal integrity at the UDMA mode 2 (and higher) speeds, so less risk of IDE bus CRC errors, which can trigger Windows to drop to PIO transfer mode.

Welcome to CDFreaks.

When the 708A came out, many people including myself experienced troubles with that drive reading all types of CDs. Some people reported very slow speeds, and others reported that it simply would not read CDs even though DVDs were fine. (My own drive was actually leaving scuff marks on CDs.) In many cases, the drive was fine and then one day (or after a f/w update) it simply would not read CDs, even if the f/w was rolled back.

The only solution was to RMA the drive.

Followup…

Here’s a URL that goes into great detail about all things DMA - M$ Knowledge Base articles etc. If you try everything and still experience the problem, yep, RMA it.

Good luck.

Just a “simpel” thing. When have you upgrade to FW 1.08 ? This “upgrade” socks http://club.cdfreaks.com/showpost.php?p=731880&postcount=1.
After install, I could not erase most brands of DVD+RW any longer (only HP disks worked). After downgrade to 1.04 - now everything is just rolling.
